Helena Petrova Blavatsky

To act wisely when the time for action comes, to wait patiently when it is time for repose, put man in accord with the tides. Ignorance of this law results in periods of unreasoning enthusiasm on the one hand, and depression on the other.

The Path that leadeth on is lighted by one fire - the light of daring burning in the heart. The more one dares, the more he shall obtain.
